Confirmed by an actual live Okta sign-in after main (cc64c88) deployed: preferred_username is the right identity claim, and the redirect URI works. Matt matched his existing pre-Okta admin account rather than getting JIT-provisioned as a duplicate. Two deploy-time snags recorded, both Case B (config, not data): OKTA_CLIENT_ID/SECRET/ISSUER left empty in Portainer at first (caught cleanly by is_configured()), then OKTA_ISSUER missing its https:// scheme (surfaced as httpx.UnsupportedProtocol, not a deliberate app error - BL-028 still stands). Neither needed the backup. BTG pilot group now includes Cody and Cameron, awaiting Adrian.
